Hyaluronic Acid Gels (HAG) have been FDA approved for the treatment of facial rhytids (wrinkles). They are injected under the skin and work by increasing volume. Recently, some smaller retrospective research studies have shown that HAG is also effective in correcting upper and lower eyelid retraction in TED. Hence, HAG may be for patients with active stage TED. It is also thought that if employed early in active phase disease, HAG may also help to decrease the severity of associated symptoms and reduce the need for surgery.
